Periodic / Harmonic Data Editor

TRANSIENT-option: Solving and evaluating time dependant dynamic, periodic problems when heat capacity effects
are concerned is
only possible with an active TRANSIENT-Option of the program.

The Periodic / Harmonic Data Editor will be
used out of the Boundary Conditions window when transient
problem is to be evaluated and time dependant boundary conditions are needed for that purpose. For convenient managing periodic
data sets it us available from a Tools Menu also.

There are following types of data which could by managed within Periodic / Harmonic Data Editor:

Constant

Regular Points

Regular Means

Irregular Means

Irregular Steps

Harmonic Coefficients.

The window contains three parts:

File & Examples Menu

Info

Graph

Data Grid

File Menu:

New - create new data set of the specific part. A dialog is shown to provide the information required for specific type
(see "Info Part").

The Info part displays the characteristic information for the dataset being processed. Depending on the type of data
different information is displayed and eventually available to input.
The initial specific values are supplied during the creation of the data set (File->New...) and a limited set of them, depending
on the data type processed, can be changed later.

Description identifying the data

Period Length (in seconds)

Number of Intervals

Number of Points

Interval Duration (in seconds)

Graph Chart Part:

The graph chart represents and displays the input data along with its synthetic variant resulting from harmonic Fourier
analysis and synthesis.

Zoom with lasso is possible by clicking in the graph with the left mouse button and dragging the cursor to another position. With the right mouse button it is possible to reset the zoom.

The legend provides the identification of patterns shown. A double click on to the legend will change its position relative
to the chart area (right, left, top, bottom).

Data points can be selected.

Data points (or bars) can be dragged changing the value (press ESC to abort the unintentional drag operation an revert to the
previous value).

MULTICORE-option: Speeding up computationally intensive jobs by distributing them on multiple processors or
processor cores for parallel execution is
only possible with an active MULTICORE-Option of the program.

Context menu of the Graph Chart:

Window Function

Cut-Off Harmonic

Window Function
(Gibbs Effect)

Selection of the windowing filter function to reduce the Gibbs effect (e.g. while working with switch
functions "IrregularIntervalSteps" or dense data with high value changes).

Fejer window

Hann window

Hamming window

None

Cut-Off Harmonic

Limits the number of harmonics for the Fourier syntheis.

Data Grid Part:

The data is input into the Value column.
The native Copy & Paste of the selected cell(s) is provided.

Capability to paste data from/to the Value column streamlines the input procedure (also available via Context Menu). All
numbers contained in the paste buffer (regardless if column(s) or row(s)) will be parsed as double entities (entries in error
and not parse able as such in be ignored) and transferred in the order to the value column.

Buttons:

With the button "Harmonics" the user can open a window where the individual components of the harmonic Fourier series are displayed in their temporal progression. The harmonic value at a given point of time is (approximately) the sum of the individual components. The user can choose which of up to twelve components should be displayed. It is also possible to assign various colours to the components.

With the camera button it is possible to create a screenshot which can later be used in the report builder. In the Harmonics window there is this possibility as well.
